Problems solved by technology

[0007] The purpose of the present invention is to promote the industrialization process of housing, and improve the existing frame shear wall structure system by using an assembled cavity prefabricated panel of cast-in-place cavity floor without formwork; fully utilizing the advantages of factory industrialization, prefabricated production The prefabricated cavity floor slab solves the problems of construction, environmental protection, weight, cost, and work efficiency in the existing system; the overall force of the building structure is solved by pouring reinforced concrete on site. Concrete is organically combined to optimize the existing frame shear wall structu

Embodiment Construction

[0023]The invention will be further described below in conjunction with the accompanying drawings.

[0024] figure 1 It is a plan view of a prefabricated cavity prefabricated slab of a cast-in-place cavity floor free from support formwork of the present invention. When the present invention is implemented, it is a prefabricated assembled cavity floor 2 that will be produced on the factory assembly line; The bottom formwork system with surrounding rails on the cavity floor is transferred to the formwork workshop and the rib steel bar and filling body workshop; the vertical formwork is installed on the bottom formwork to form an open base formwork of the required specification and model, and placed in the open base formwork Rib beam reinforcement, ribbed steel mesh engraving, willow mold, through pipes between rib beams, etc.; then transfer the bottom form system with surrounding tracks to the pouring workshop. The computer automatically mixes cement, sand, and stone according t...

Abstract

The invention provides an assembly type cavity prefabricated slab of a formwork-erecting-free cast-in-situ cavity floor system. The assembly type cavity prefabricated slab comprises a reinforced concrete ribbed beam, a reinforced concrete upper flange plate, a reinforced concrete lower flange plate and filler. The reinforced concrete ribbed beam internally comprises at least two longitudinal reinforced concrete ribbed beam bodies and multiple transverse reinforced concrete ribbed beam bodies. The two ends of reinforcements of the longitudinal reinforced concrete ribbed beam bodies are exposed out. Multiple annular reinforcements are arranged on the upper surface of the reinforced concrete ribbed beam. The filler is a polyphenyl block or a plastic cavity or a cement cavity or a slab cavity or an empty net cage. The filler of the assembly type cavity prefabricated slab of the formwork-erecting-free cast-in-situ cavity floor system is exposed out of the upper surface. The assembly type cavity floor slab produced through the process is high in integrity, reasonable in structure, high in quality standard, controlled in procedure and good in self-heat-preservation and self-sound-insulation performance.

Description

technical field [0001] The invention relates to a housing industrialization system technology, in particular to an assembled cavity prefabricated panel technology for a mold-free cast-in-place cavity floor. Background technique [0002] In the 1980s, the production of concrete prefabricated components in my country was in a stage of great development. In the process of housing construction, the country adopted hollow prefabricated slab structures, large slab structures, cast-in-place concrete structures, cast-in-place concrete hollow floor slab structures, and cast-in-place frame shear forces. Wall structure, etc. With the process of housing industrialization, steel-concrete composite structure and steel-concrete composite cavity floor structure system have been developed rapidly. [0003] For example, the ZL98231113.3 concrete thin-walled cylindrical member declared by the applicant is made into a sealed cylindrical filling body, which provides a tubular hollow filling body ...
